Antenna Description


Combining Durability, Performance and Design with Full Access to the World’s Largest Network

2J Antennas takes pride in the quality of our antenna products and we are pleased to offer the High-Performance Iridium Certified Screw Mount Antenna (2J9126BW) that is designed specifically for marine applications. With waterproof housing, this antenna combines durability, exceptional connectivity and design appeal for voice and data satellite communications that require mission-critical reliability with full access to the world’s farthest-reaching Iridium network. 

The fixed 2J9126BW works well with repeaters designed to extend the reception of handheld voice and data devices. This antenna was designed to  deliver exceptional connectivity for permanent marine or land applications exposed to extremely harsh and remote environments. 

With a high peak gain of ~4.5 dBi and ~76% consistent efficiency, this antenna assures reliable signal strength within the 1616 MHz – 1627 MHz hemispherical frequency spectrum. This antenna is right hand circular polarized (RHCP) with a <3 dB axial ratio. 


Suggested applications include:

- Satellite Communication
- Commercial or Leisure Marine
- Emergency/ Safety Critical Communication
- Transportation



Installation / Environmental

The IP67 waterproof antenna housing and base are manufactured with UV stable ABS material offering protection and resistance to dust, sand, particles, and water ingress making it an ideal solution for extreme environments with temperatures ranging between -40 C to +85 C. Designed with dimensions of Ø 74 × 34.7 mm and a low profile, this antenna can be permanently installed with three screw mounts securing the antenna to any free space without the need for grounding. 

The 2J9126BW comes with a standard SMA-Male connector and a 300cm long LL195W cable designed for short cable runs while maintaining excellent performance. We offer a wide range of alternative connectors and cables for any customization needs to help our customers optimize marine application needs. Please contact us for any request or antenna selection needs.

All our products are designed with the environment in mind and manufactured without hazardous materials with full REACH and RoHS compliance.
